Safety Integrated 3

Safety Integrated Customized safety solutions for any automation task

With its range of safety components, Siemens is able to offer a customized safety solution for almost any application: this includes both stand-alone solutions in simple automation tasks and integrated solutions with a higher-level controller in comprehensive automation applications.

Stand-alone safety solutions for small to medium-sized automation tasks

For small automation solutions, it is often sufficient to con-nect (hardwire) a limited number of safety-related compo-nents to an evaluation unit. To do this, you can use either the SIRIUS 3TK28 safety relay or a modular SIRIUS 3RK3 safety system. As an alternative to the 3TK28, safety-relevant signals can be evaluated via the AS-i bus using the AS-i safety monitor.

Stand-alone solution

Integrated safety solutions for production automation with SIMATICThe SIMATIC automation system plays a central role in pro-cessing and coordinating safety-relevant processes in indus-trial automation and it is now the standard in many instances. The Safety Integrated portfolio is harmonized along these lines so that applications can be integrally designed: a SIMATIC operates without any problems in conjunction with the drive technology (SINAMICS, SIMATIC ET 200), low-volt-age switchgear and controlgear (SIRIUS), and sensors (SIMATIC Sensors) from Siemens. Communication is carried out via PROFIBUS or PROFINET using the PROFIsafe standard.

Integrated safety solution with SIMATIC

Integrated safety solutions for machine tools with SINUMERIKThe integrated safety functions of SINUMERIK Safety Integrat-ed are used in the machine tools sector. They are redundantly integrated in NC 1), the drive and the internal PLC and are used to monitor speed, standstill, and position. Such monitoring is necessary if the danger zone of the machines and systems is not blocked off. However, even in test mode or production mode, it provides effective operator protection as well as pro-tection of tools, materials, and machines.

Integrated safety solution with SINUMERIK

In machines and systems, automated movements present huge potential risks. For this reason, drives always play a central role in safety solutions, regardless of the complexity of an automation task. Siemens drives are designed in such a way that they can be easily integrated into any of the safety solutions shown. With their integrated safety functions, they provide the basis for implementing highly effective safety concepts.

Advantages of drive-integrated safety functions4

Advantages of drive-integrated safety functions

Electrically driven assemblies and machine components often pose a huge potential risk. Rotating units such as saws, rollers and spindles can cause serious or even fatal injuries. The same applies to machine units that have a linear motion such as handling axes and machine slides. The measures for guaranteeing the safety of the operating personnel are governed by country-specific regulations.

When drives without integrated safety technology are used, operator protection was previously implemented through the use of additional hardware components such as contactors and safety relays, and interlock circuits. In danger situations, the systems are simply shut down and they have to be restart-ed later. This sometimes leads to long downtimes and has a negative impact on productivity. At the worst, the operator is tempted to manipulate the safety devices.

In modern drives, safety functions are becoming increasingly integrated. Using drives with integrated safety technology can mean that previously required electromechanical components and their associated wiring can be omitted. Even the transmis-sion of safety-relevant signals can be done via standard field-buses, which also reduces the complexity and overhead of wiring. This considerably simplifies the implementation of safety concepts. In addition, they allow for considerably more efficient safety concepts, both in terms of functionality and in terms of response times. This often even causes an increase in productivity.

The use of certified integrated safety functions simplifies the certification of the safety category that is required for a ma-chine. The user is additionally supported by the online safety evaluation tool to meet this requirement (see www.siemens.com/safety-evaluation-tool).

The most important integrated safety functions for drives 5

The most important integrated safety functions for drivesDescription, possible application areas, and advantages for the customer

The implementation of safety concepts is based on the idea that safety-relevant events will first be detected, then evaluat-ed, and then reacted upon accordingly. An overview of the Siemens components available for this purpose can be found in the table on page 2.

Fail-safe drives are characterized by their "integrated safety functions", which they provide to the user as possible respons-es to safety-relevant events. The most important integrated safety functions available for Siemens drives are described in the following. The functional safety of all of the functions satisfies the requirements defined in Part 5-2 of the interna-tional standard IEC 61800 for variable-speed drive systems.

The drive-integrated safety functions can be roughly divided into two categories:

Functions for safely stopping the drive without having to disconnect the power line. This includes the following functions:

• Safe Torque Off (STO): This function ensures that the motor shaft does not produce any torque.

• Safe Stop 1 (SS1): This function actively decelerates a drive before the STO function is activated. In the event of danger, drives with a high kinetic energy can be brought to a standstill extremely quickly using this function.

• Safe Stop 2 (SS2):Like the SS1 function, the SS2 function actively decelerates the drive. In standstill, however, the SOS function is used instead of STO. Just as with SS1, drives with a high kinetic energy can be brought to a standstill extremely quickly in a hazardous situation.

• Safe Operating Stop (SOS): As an alternative to STO, you can use the SOS function. In contrast to STO, the motor is not released from all torque. Instead, the drive remains in position control, holds its position, and it is monitored to generate zero speed.

• Safe Brake Control (SBC): This function safely applies a holding brake after STO is activated, which means that the drive can no longer move, e.g. due to gravity.

Functions for safely monitoring the speed of a drive:

• Safely Limited Speed (SLS): This function monitors the drive to detect if it exceeds one or more specified maximum speeds.

• Safe Speed Monitor (SSM): This function reports if the rotation speed goes below a specified speed. No drive-autonomous response occurs.

Further additional safety functions are available specially for safety solutions in machine tools in connection with the SINUMERIK CNC.

• Safely Limited Position (SLP):This function prevents a specified position from being exceeded. With this function, a work area / protected area limitation or traversing range limitation can be imple-mented for specific axes.

• Safe Cam (SCA): This function outputs a safe signal if the drive is within a specified position range. This function can be used to im-plement a reliable range recognition for specific axes.

• Safe brake management:Safe brake management consists of a safe braking signal and a safe brake test. The safely activated and tested brake, in combination with the safely monitored drive, results in a redundant stopping system for fall protection at vertical axes.

• Safe programmable logic:Using safe programmable logic, it is possible to connect safety-related sensors and actuators directly to the control unit's I/O, without external evaluation units, and to evalu-ate them using software.

The most important integrated safety functions for drives6

The most important integrated safety functions for drivesDescription, possible application areas, and advantages for the customer

Safe Torque Off (STO)

The STO function is the most common and basic drive-inte-grated safety function. It ensures that no torque-generating energy can continue to affect a motor and prevents uninten-tional start-ups.

DescriptionThis function is a mechanism that prevents the drive from restarting unexpectedly, in accordance with EN 60204-1, Section 5.4. Safe Torque Off disables the drive pulses and disconnects the power supply to the motor (corresponds to Stop Category 0 of EN 60204-1). The drive is reliably torque-free. This state is monitored internally in the drive.

ApplicationsSTO has the immediate effect that the drive cannot supply any torque-generating energy. STO can be used wherever the drive will naturally reach a standstill due to load torque or friction in a sufficiently short time or when "coasting down" of the drive will not have any relevance for safety.

Customer benefitsThe advantage of the integrated STO safety function com-pared to standard safety technology using electromechanical switchgear is the elimination of separate components and the effort that would be required to wire and service them. Because of the rapid electronic switching times, the function has a shorter switching time than the electromechanical com-ponents in a conventional solution.

Safe Stop 1 (SS1)

The SS1 function causes a motor to stop rapidly and safely and switches the motor to torque-free mode after the standstill, i.e. STO is activated.

DescriptionThe Safe Stop 1 function can safely stop the drive in accor-dance with EN 60204-1, Stop Category 1. When the SS1 function is selected, the drive decelerates along a quick stop ramp autonomously and automatically activates the Safe Torque Off and Safe Brake Control functions (if enabled) when a parameterized safety delay timer runs down.

ApplicationsThe SS1 function is used when in the event of a safety-rele-vant incident the drive must stop as quickly as possible with a subsequent transition into the STO state. It is thus used to bring large centrifugal masses to a stop as quickly as possible for the safety of operating personnel, or to brake motors at high speeds as quickly as possible. Typical application examples include: • Saws, grinding machine spindles, centrifuges, stacker

cranes

Customer benefitsThe targeted stopping of a drive by means of SS1 reduces the risk of danger, increases the productivity of a machine, and allows safety clearances in a machine to be reduced. The reason is the active stopping of the drive compared to the use of the STO function alone.Elaborate, wear-prone mechanical brakes for stopping the motor as quickly as possible are not required.

The most important integrated safety functions for drives 7

Safe Operating Stop (SOS)

With the SOS function, the stopped motor is brought into position and monitored by a drive control.

DescriptionThe Safe Operating Stop function represents safe standstill monitoring. The drive control remains in operation. The motor can therefore deliver the full torque to hold the current posi-tion. The actual position is reliably monitored. In contrast to safety functions SS1 and SS2, the speed setpoint is not influ-enced automatically. After SOS has been activated, the higher-level control must bring the drive to a standstill within a parameterized time and then hold the position setpoint.

ApplicationsSOS is an ideal solution for all those applications for which the machine or parts of the machine must be at a safe standstill for certain machining steps, but the drive must also supply a holding torque. It is ensured that despite counter torque the drive remains in its current position. In contrast to SS1 and SS2, the drive does not brake automatically in this case. It expects the higher-level controller to coast down the rele-vant axes as a coordinated group within an adjustable delay time. This can be used to prevent any damage to the machine or product.

Customer benefitsNo mechanical components are necessary to keep the axis in position despite any counterforce that might appear. Due to the short switching times and the fact that the position con-trol always remains active, setup and downtimes are reduced. Recalibration of the axis after exiting the SOS function is not necessary. The axis can immediately be moved again after deactivation of the SOS function.

Safe Stop 2 (SS2)

The SS2 function shuts down a motor quickly and safely and then monitors the standstill position.

DescriptionThe Safe Stop 2 function can safely stop the drive in accor-dance with EN 60204-1, Stop Category 2. When the SS2 func-tion is selected, the drive decelerates autonomously along a quick-stop ramp. In contrast to SS1, the automatic speed con-trol remains operational afterwards, i.e. the motor can supply the full torque required to maintain zero speed. Standstill is safely monitored (Safe Operating Stop function).

ApplicationsAs with SS1, the SS2 function ensures the quickest possible deceleration of the motor. However, the motor power is not switched off, but prevented by a control system from leaving the standstill position even if affected by external forces.

Customer benefitsThe SS2 function ensures a rapid axis stop. Because the control remains active, after the safety function is deselected, productive operation can continue without referencing. This ensures short setup and standstill times and high productivity.

The most important integrated safety functions for drives8

The most important integrated safety functions for drivesDescription, possible application areas, and advantages for the customer

Safe Brake Control (SBC)

The SBC function permits the safe control of a holding brake. SBC is always activated in parallel with STO.

DescriptionA holding brake which is active in a de-energized state is controlled and monitored using safe two-channel technology. Due to the two-channel control, the brake may still be activat-ed in the event of an insulation fault in the control cable. Errors of this kind are detected early by means of test pulses.

ApplicationThe SBC function is used in conjunction with the functions STO or SS1 to prevent the movement of an axis in the torque-free state, e.g. because of gravity.

Customer benefitsAgain, the function saves the use of external hardware and the associated wiring.

Safely Limited Speed (SLS)

The SLS function ensures that the drive does not exceed a preset speed limit.

DescriptionIf the preset speed limit is exceeded, this is detected reliably. If the limit is exceeded, a customizable drive-independent fault reaction occurs.

ApplicationThe SLS function is used if people are in the danger zone of a machine and their safety can only be guaranteed by reduced speed. First, therefore, the speed is reduced, then safe moni-toring is activated using the SLS function so that accidental exceeding of the set speed limit is prevented. Typical exam-ples are cases in which an operator must enter the danger zone of the machine for maintenance or setup. A typical use of SLS is a winder, in which the material is manually threaded by the operator. To prevent injury to the operator, the roller may only spin at a safe reduced speed. SLS is often also used as part of a two-stage safety concept. While a person is in a less critical zone, the SLS function is activated, and the drives are only stopped in a smaller area with higher potential risk. SLS can be used not only for operator protection, but also for machinery protection, e.g. if a maximum speed must not be exceeded.

Customer benefitsThe SLS function can contribute to a significant reduction in downtime, or greatly simplify or even accelerate setup. The overall effect achieved is a higher availability of a facility. Moreover, external components such as speed monitors can be omitted.

Safe Speed Monitor (SSM)

The SSM function warns when a drive is working below a specified speed / feed speed. As long as it remains below the threshold, the function issues a safety signal.

DescriptionIf a speed value drops below a parameterized level, a safety signal is generated. This can be processed, for example, in a safety controller to react to the event by programming, depending on the situation.

ApplicationWith the SSM function, in the simplest case, a safety door can be unlocked if the speed drops below a non-critical level.

Customer benefitsUnlike SLS, there is no drive-independent fault reaction when the speed limit is exceeded.The safe feedback can be evaluated in a safety control unit, allowing the user to react appropriately to the situation.

Safety motor startersFor applications with fixed speed

Safety motor starter SIMATIC ET 200S

Safety motor starter SIMATIC ET 200pro

If an application only needs to operate motors in network mode with a fixed speed, motor starters are used to control the motors, to limit start-up currents, and for soft starting. In addition to the individual devices from the SIRIUS product family, Siemens offers motor starters integrated into the SIMATIC ET 200 I/O system, specifically for use in a SIMATIC environment. These are especially useful for use in materials handling applications with multiple motors, for example in the automotive field. The STO safety function can be optional-ly implemented with the motor starters of the SIMATIC ET 200S / ET 200pro I/O systems via an add-on module.

■ SIMATIC ET 200S motor starter Motor starter for the ET 200S I/O system with IP20 degree of protection for switching up to 7.5 kW.

■ SIMATIC ET 200pro motor starter Motor starter for the ET 200pro I/O system with the high IP65 degree of protection for switching up to 5.5 kW.

The motor starters are fully integrated with the SIMATIC ET 200S / ET 200pro I/O systems, both in terms of construction and data. Mounting, wiring, and commissioning can thus be implemented very efficiently. The motor starters utilize the system mechanisms of these I/O systems and thus also simplify diagnostics in the event of a fault.

Most important features:

• Switching of three-phase induction motors as direct starter, reversing switch, reversing starter

• Simple assembly and wiring • Simple setup of multi-motor drive solutions by self-assem-

bling communication and supply rails in the backplane bus• Efficient diagnostics

IP20 and IP65 degrees of protection represent two essentially different available safety concepts:

■ SAFETY MOTOR STARTER SOLUTIONS LOCAL are the ideal systems for locally limited safety applica-tions. They function autonomously and are therefore not dependent on a safe control.

■ SAFETY MOTOR STARTER SOLUTIONS PROFIsafe in combination with a safe control and the PROFIBUS or PROFINET bus systems offer optimal solutions for the most demanding and networked safety applications.

The control of the safety functions via PROFIBUS DP or PROFINET is possible by using a PROFIsafe profile. The motor starters are certified according to EN 954-1, Category 4, and IEC 61508 SIL3.

SIMATIC ET 200pro FC / SIMATIC ET 200S FC – frequency converters integrated with the ET 200 I/O sys-tem for use with PLCs

SIMATIC ET 200pro FC and SIMATIC ET 200S FC

Complementing the frequency converters of the SINAMICS drive family, Siemens also offers frequency converters inte-grated in the SIMATIC ET 200 I/O system specifically for use in a SIMATIC environment. They are also optionally available with integrated safety features.

■ SIMATIC ET 200S FC frequency converters with IP20 degree of protection with power ratings up to 4 kW.

■ SIMATIC ET 200pro FC frequency converters with high IP65 degree of protec-tion with power ratings up to 1.5 kW.

The converters are fully integrated with the SIMATIC ET 200S / ET 200pro I/O systems, both in terms of construction and data. Mounting, wiring, and commissioning can thus be imple-mented very efficiently. The converters utilize the system mechanisms of these I/O systems and thus also simplify diag-nostics in the event of a fault.

Most important features:

• Variable-speed operation of induction motors using V/f or vector control for power ratings up to:- 4 kW (SIMATIC ET 200S FC)- 1.5 kW (SIMATIC ET 200pro FC)

• Torque control• Degree of protection

- SIMATIC ET 200S FC: IP20- SIMATIC ET 200pro FC: IP65

• Energy-efficient operation through energy recovery (op-tion)

• Simple setup of multi-motor drive solutions by self-assem-bling communication and supply rails in the backplane bus

• Efficient diagnostics

STO, SS1, and SLS are available as integrated safety functions. The SS1 and SLS functions do not require an encoder1). The control of the safety functions via PROFIBUS DP or PROFINET is possible by using the PROFIsafe profile. The integrated safety functions are certified in accordance with EN 954-1, Category 3, IEC 61508 SIL2 and EN ISO 13849-1 PL d.

1) SS1 and SLS are not allowed in encoderless operation for drawing loads such as hoisting gear or unwinders. Here, the SS2 function is required (see SINAMICS S120).

High performance and motion control drives with integrated safety functions16

High performance and motion control drives with integrated safety functionsFor demanding single and multi-axis applications

Siemens offers drives with integrated safety functions for every kind of demanding application.

Given the often rapid movement sequences, the high forces, and the sometimes large moving masses, the short delay times of integrated safety functions also offer a much higher level of protection against personal injury and material dam-age than conventional safety concepts. In addition, complete-ly new safety functions that were not previously possible allow the implementation of entirely new safety concepts in a cost-effective manner.

The result is machines and equipment that increase safety without a serious reduction in productivity.

The following drives are available:

■ SINAMICS S110 the single-axis drive for simple positioning tasks

■ SINAMICS S120 the drive system for demanding and high-performance applications

■ SINAMICS S150 the converter cabinet for demanding, speed-changing single drives.

Together with other safety components, the SINAMICS S110 and SINAMICS S120 can be integrated in automation solutions that satisfy the highest safety requirements either by means of fixed wiring or – even simpler – via a standard fieldbus using the PROFIsafe profile .

Typical configuration of a motion control drive configuration based on SINAMICS S120 drives with integrated safety features

The image shows a typical configuration for implementing a safety concept with SINAMICS S120.

• Safety-related incidents are triggered by light curtains, laser scanners, position switches, and other safety compo-nents.

• The detection and transmission of signals occurs via digital inputs through fixed wiring or directly via a fieldbus to a higher-level safety control.

• Safety-related signals are processed in the higher-level control such as the SIMATIC S7-315F.

• This in turn, depending on the situation, activates the relevant safety-related function in the SINAMICS S120 drive system via transmission over the bus system.

• Various integrated safety functions are available in the drive. The selection of the individual safety functions is done by setting the appropriate bits in the PROFIsafe proto-col. Integrated safety functions are triggered for single drive axes, or even complete axis groups.

Based on the outlined system concept, flexible and powerful safety concepts are feasible without major wiring effort. First, the statutory safety regulations applicable to one machine type can be implemented in a simple way. Moreover, the avail-ability of higher-quality safety features such as Safely Limited Speed allows the easy implementation of additional safety features, especially for maintenance and setup. The safety hazard for the operator remains low, without affecting the productivity of the plant.
